| description.abstract | The crystal structures of Ph3Te(μ-S2COMe)2TePh3 (1) and Ph3Te(S2CO(iBu)) (2) have been determined by X-ray diffraction. The two xanthate ligands bridge the two tellurium atoms in triphenyltellurium(IV) methylxanthate. The coordination environment around each Te atom of 1 is a distorted octahedron. The three Te---C (phenyl) carbon atoms form one fac set and the two Te---S bonds along with the lone pair form the other. The Te---S bonds are long, suggesting that they are weak. The xanthate ligand in 2 is chelated with tellurium. The chelation of the iBUOCS−2 skeleton is asymmetric and weak, the Te---S bond lengths being 3.535(4) and 3.123(4) Å. The change in the mode of coordination of the xanthate ligand arises from the greater steric influence of the iBu group. | en |
